Abstract of the Disclosure Process for making wrought, recrystallized, lead- calcium, battery grid alloy having high temperature tensile strength stability and excellent corrosion resistance involving rapidly, unidirectionally, cold rolling a cast lead alloy strip containing about 0.07% to about 0.11% by weight calcium and up to about 1.5% by weight tin. The rolling of the alloys is done such as to strain harden them before any significant strain aging thereof can occur during rolling and such that the strip recrystallizes at room temperature to a fine grained microstructure within about 30 days after rolling; has both room and high temperature (i.e., 150°F.) tensile strength stability greater than 5000 psi; and has small islands of a structureless phase distributed throughout the microstructure for reducing intergranular corrosion. Alloys containing up to about 0.35% tin may be rolled by a variety of schedules to produce this result. Alloys containing over 0.35% tin are rolled by a reduction schedule having at least six (6) reductions of about equal thickness.
